Hi, Please advice us the best RAID we can used for our data disk (chunk). we install IDS 12.10 on HP-UX platform, Our dbspaces we used SAN storage (HP 3PAR). Curently we used RAID-5 for our data dbspaces (RAW format). HP-3PAR Right now give option to using RAID1+0, Which Raid configuration better for data disk to get best performance. Thank You

Mohd: NO RAID5!!! You should be using only RAID 1 or RAID 10 for database storage for safety and performance, but mostly for data safety! Please see my paper on the evils of RAID5 on my web site at www.askdbmgt.com/why-raid5-should-be-avoided-at-all-costs.html. You can also find similar papers by others at www.baarf.com. Check out the membership list at the BAARF site. When you join BAARF you get to add a comment about why you joined. You will see brief comments from hundreds of DBAs who have been bitten by RAID5 data loss. NO RAID5!!! NO RAID5!!! NO RAID5!!! NO RAID5!!! NO RAID5!!! NO RAID5!!! NO RAID5!!! NO RAID5!!! NO RAID5!!!
